; To all whom tt may concern.- p

Be it known that I, THEODORE of Yonkers, countyof Westchester, and State of NewYork, have invented a certain new and y l usefulmprovement in Ribbon-Paper-Printing l "Machines, ofwhich the following is a full,

clear, and exact description, reference being had to the` accompanying drawings, forming part thereof. l i v 1o Theinvention relates toprinting-machines especially adapted to print measurements and other matter on ribbon-paper which is wound i in a roll with the ribbonandrepresents thelength thereof. n i In the accompanying drawings, in which similar lettersofreierenee indicate like parts, Figure l is a side elevation of my invention; Fig. 2 is a top view ofthe same, and Fig. 3 is 1 a sectional view on the line .r m of Fig. l. On upright suitably-shaped frames AandA,

afl, and c5, constituting thereby the main frame,

\ are bearings in which revolves the shaft B, by means of a crank, orpnlleys if driven by steam.

z 5 To this shaft Bis fastened, by any well-known "means, a cylinder or drum, O, which has gearteeth "b on its periphery at one end, which work in corresponding teeth b on the impression and feed cylinder D, placed immediately 3c above `the cylinder or drum C, `and which impression-cylinder rotates loosely on an eccentric spindle, c, having its bearings on frames p A and A. inthe samedhorizontal plane in which thespindle c lies are spindles c and c2,

on which revolve loosely the rollers E and E, on each side ofthe impression-cylinder D, and `which are geared by teeth b2`and b3` in teeth b',onsaid,impression-cylinder D. Theimpresi l sion-cylinder D and rollers E and E consti-` 4o tute `the feeding ,i arrangementfor the paper to be printed, which comes from a roll ot4 paper, R, hung on al roller-,RQ which rotates in `bearings on extended armsjud` d of frames A i A'. On a similar,` roller, R2, on similar extended `arms d d', thepaper is wound up y lagain after leaving the rollers E and E and impression-cylinder D.` n

Toa partition, c, in the cylinderor dru n10 are i `four (or more or less, as desired) pedestals, e',

carry each a consecutive numbering and marking Wheehj', revolving on a pin, g,in the pedestals c. Thetype or electroplates e2 are fastened to the faces of the wheelsj'in any well-known manner, and so that the face ofthe type, when 5 5 passing the impression-cylinder D, stands di-. rectlynnder it, and leaves an impression en the paper which is carried by cylinder D. This impression-cylinder D consists of a rubis cast on a hollow shell, o', which rotates loosely on eccentric spindle c.`

In a recesson one side of theconsecutive numbering and marking wheel f, and secured to it, isaratchet, h. A lever, h2, swinging from the same center as the numbering-wheel does, carries a pawl, h', and a spring, It, which pawl h' Works in ratchet h, and is kept in contact with it by spring h6. The lever l1,2 is ball-shaped on its outer end, and when the 7o cylinder or drum O is revolved, and with it the pedestals c and attachments, this ball enters and passes through a cam-groove, fi, fastened tothe inner side of frame A. The shape of the cani-groove t' causes the lever h2, on` its 75 passage through said cam-groove, 'to oscillate on its axis g, whereby the consecutive-numberingwheels, through the action of pawls h and ratchets h, are moved on their spindles g. On the other side of the numbering-wheelf is 8o `a ring, h3, having V-shaped notches, in which fits a V-shaped boss on a spring, h4, secured to the pedestal e'. The object of this arrangementis to keep the numbering-wheels tight and firm when the lever h2 is not in contact 85 with the cam-groovefi and when the impression is being taken. A spring, h5, also fastened to the pedestal c', reaches overaiiattened side of lever h2, and keeps it in proper position when its ball end is out of cam-groove t'. 9o

The inking arrangement consists of an oscillating ink-fountain, F, and stationary frame G, which carries the inking-rollers Hand H and the distributing-roller I. The ink-fountain F swings on girt a?, and has an exten 95 sion, i', downward, reaching to girtc. At the end of this extension i is a set-scremvtz, having its inner end resting on girt c3, and servi l fastened equal distances from each other, which 5o G; HosrEn, l

ber covering, o, without screws or joints, and 6o n ing as a regulator for the throw of the fountain. A spring, 5, screwed at one end to girt a?, and the other end resting on the front of extension i', moves the fountain back again when swung out of position.

An L-shaped lever, F, swinging on the same girt a2, is connected to the fountainframe F by a set-screw, i3, (on its smaller arm 1,) screwed in aboss, i4, on the fountain-frame. The incline of arm l of lever F reaches to the cylinder or drum G, and a pin, Z2, s ecured to the latter in its periphery, strikes the incline of arm l' when said cylinder or drum O is rotated and oscillates the ink-fountain, so that the fountain-roller N touches the distributing-roller I and delivers its ink, while spring 5 brings fountain F and lever F into their former positions when the pin Z2 has left the incline of arm l.

The ink-fountain roller N is turned by a ratchet, m, on its shaft, outside of the fountain-frame F, and a pawl, m', fastened on the frame G, when the fountain F oscillates toward the frame G.

The composition or inkin g rollers H and H turn loosely on eccentric spindles c3 and c,which have their bearings in frame G, and receive a rotating motion by their respective gear-wheels b4 and b5 being geared in teeth b on the main cylinder or drum C. Between these inkingrollers H and H lies the distributing-roller I, which is mounted on shaft J, and is turned with the same by having gear-wheel b5, fastened on shaft J, geared in wheels b4 and b5 on the inking-rollers. A distributing or sliding motion of the distributing-roller I is obtained by a stationary roller or piu, a5, on an arm, n4, fastened to frame G, said roller or pin working in a groove, n3, on roller I. A key on shaft yJ turns the loose distributing-roller I when said shaft is rotated by gear-wheel be, as before stated, and also allows a sliding or sidewise motion of said roller I on said shaft'J, which motion is obtained by the action of roller or pin a5 in groove nl.

The rewindin g of the paper is accomplished by means of a grooved pulley, p, on the shaft of roller R2, over which runs a belt, p', to the driving-pulley on shaft B.

On girts a and a are adjustable collars r r and r 1", which serve to guide the paper directly to the feeding-rollers E E and impression-cylinder D, and admit of being adjusted to the different widths of the paper to be printed.

The operation of this machine is as follows: The paper from the roll R is passed under girt wand between the collars i" i", over roller E, and under and between impression-eylinderD and drum or cylinder C, then over roller E', then under girt a.' and between collars r rf, up to the rewinding-roll R2,to which itis, by some known devices, fastened to be rewound.

To adjust the impression, the eccentric spindle c is turned, thereby moving the impressioncylinder D to or from the form-cylinder C, as

desired. The spindle c is then heldin such position by fastening set-screw s. The feedrollersE and E', which work ateach side of the impression -eylinder D, are adjusted to suit and feed they various thicknesses of paper by turning their respective spindles c and e2, and are then fastened in the desired position by set-screws s and s2, in the same manner as spindle o.

Now, if the shaft B is set in motion, it rofates the drum or cylinder C, and, through t-he gears b and b', transmits motion to impression-cylinder D, which in turn transmits its motion, by gears b', b2, and b3, to the rollers E and E'. Said rollers E and Ef and said impression-eylimler D will continually unwind and feed the paper from the roll R, and it will be rewouud on R2 by the belt p and pulleyp on roll R2.

The consecutive numbering and lnarking wheelsf,f,f2,andf3 will make their impressions on the paper when passing under the paper and the rubber impression-cylinder D, and will be shifted to the next number through the action of the end of the ball-shaped 4lever h2, its pawl h', and the ratchet h on the numbering-wheels when said lever is entering in and passing through the cam-groove i, and oscillates on its axis g, so that the pawl h moves the ratchet 7L one tooth, and consequent-ly, as the numberings on the wheels correspond with the number of teeth on the ratchet, shifts the numbering-wheel to the next number, which is repeated by .each revolution of the drum or cylinder C.

When the pin Z2 strikes and passes over the incline of arm l on lever F the fountain-roll N is moved against the distributing-roller I and delivers its ink, which is in turn taken up by the inking-rollers H and H', which ink the consecutive-numberin g wheels f,f, f2, and f3 when they are passing by on their way to make theimpression. The spring 5 oscillates the fountain back again into its original position when the pin Z2 has left theiucline of arm l.

By each movement of the fountain-frame F the fountain-roll N is also turned a little by the action of the ratchet m on its striking against the stationary pawl m', secured. to frame G. If more `or less ink is desired the spring-plate t is screwed looser or tighter against the fountain-roll N, thereby allowing the latter to take more or less ink over to the distributing-roller I.

In order to assure a uniform inking of the consecutive numbering and marking wheels, the inking-rollers H and H turn loosely on eccentric spindles c3 and c4, which, when turned,

bring the inking-rollers H and H in such recarry, respectively, the impression-cylinder D `and which require a separate adjustment or setting of the impression-cylinder D and rollers E and E relatively to each other, and ofthe impressioncylinder D relatively to the consecutive-numbering wheels. By this arrangement the operator of the machine is able to make a `quick adjustment of the diierentrollers E and E and impression-cylinder D when the thickness of paper is changed.

In order to accomplish the printing of the instance-in the'right spaces of measurement I make the circumference of an imaginary circle` drawn over the faces of the type, when goutsideof the cylinder C, from the center of the cylinder or drum exactly one yard, so that one type of one consecutive-numbering Wheel,

making one revolution with the drum, measures and prints offen the paper one yard,and by the next revolution the same consecutivenumbering wheel, changing to the next number, as before described, measures and prints off two yards, and so on-that is, one yard in measurement by each revolution` and consecutive numbers of yards by the farther revolutionsuntil the consecutive-numbering wheel has itself made a revolution around its own axis, `when it will commence again to print one yard, two yards, and so on. The next consecutive-numbering wheel, f', has `as consecutive numbers and marks yard,7 l

yard,7 25,1; yards,77 and so on. i

The numbering-wheel f2 has the halves in consecutive numbers, and numberingwheel f3 has the three-quarte`rs in consecutive numbers, so that inthis case, as represented in the drawings, I print by one revolution of the drum C one yard, which is divided in exact quarters, halves, three-quarters, and yards; but I do not limit myself to only four consecutive-numbering Wheels, las I may increase or dimish the number ot Wheels, so as to make more or less divisions of the yard; nor do I limit myself to making the imaginary circle around the face of the type on the drum one yard, `as I may also increase or diminish itin yards or change it to any other system of measurement-as, for instance, the metric;

In order to print a strip ot' paper in the same lengths of another size than ten yards, as in this case isrepresented in the drawings,

I increase or diminish the divisions of numbers on the consecutive-numbering wheels and divisions of teeth on the ratchets on them to a corresponding number, and regulate the throw of' lever h2 accordingly.

To the periphery of the drum or cylinder G, and between and in line with the dierent consecutivennmbering wheels, I may fasten type of the same height as the type on the consecutive-numberin g Wheels above the drum, for printing advertisements or other matter, which would he repeatedevery revolution and printed between each yard on the paper.

I claiml. In a ribbon-paperprinting machine, th form-cylinder C, carrying the consecutive numbering and marking wheels j', f', f2, and f3, as described, in combination with the feeding arrangement, consisting of rollers E and E', rotating loosely on eccentric spindles c and c2,
